FIVE-DIMENSIONAL ASSESSMENT MODEL FOR OPERATION AND MAINTENANCE OF STORMWATER CONTROL MEASURES - TOOL FOR STRATEGIC PLANNING AND CRISIS MANAGEMENT

Most stormwater infrastructures are aging and deteriorating in the United States. The American Society of Civil Engineers (ASCE) announced its 2021 Report Card for America's Infrastructure that infrastructure has received a 'D' grade. primary study objective is to help decision-makers deal effectively with control measures limited-budgeted, ambiguous inconsistently applied operation maintenance infrastructures. A five-dimensional assessment model (5D-SAM) was developed, including location, quality, time/quantity, cost, environmental aspects. very effective helping identify current conditions, predict future state, manage quantity improve quality runoff most cost-effective manner. It helps determine whether distressed system beneficial be demolished or it would either repair, rehabilitate retrofit. Moreover, can utilized fast accurate better resource allocation strategic planning
